Guangdong Tianyi HD: Why Upgrade 4K Smart STB
"I bought a 4K TV, but I didn’t have any 4K movies or shows. It felt kind of tasteless," one user said. Another shared, "I tried to watch a 4K blockbuster on my TV, but the set-top box didn’t support it. It was really awkward!" These are common complaints from many users who find themselves in a situation where their TVs are more advanced than the content they can access.
However, things are about to change. Guangdong China Telecom has recently launched a 4K smart set-top box upgrade service for its Tianyi HD users across the province. Both new and existing users can now easily complete the upgrade directly through their TV platforms—just go to Home > Click 4K Upgrade. For more information, call customer service at 10000.
After comparing the differences between 4K smart set-top boxes and traditional HD or SD models, it's clear that upgrading to a 4K device is not just a trend—it’s an inevitable step toward better home entertainment experiences.
**1. 4K Ultra HD: Crisp and Clear Details**
When compared side by side, the 4K smart set-top box outperforms others in picture clarity, color saturation, depth, and detail rendering. The image quality is incredibly vivid, and even small textures like whale skin become clearly visible. Watching your favorite celebrities in 4K Ultra HD means you can see every pore and detail up close.
**2. Exclusive High-Speed Channels: Smooth Streaming for Games and Movies**
One of the biggest frustrations when gaming or streaming is lag and buffering. With the upgraded 4K set-top box, users get exclusive high-speed network channels that ensure smooth playback, whether you're watching a movie or playing a game. No more interruptions or delays.
**3. Future-Ready Upgrade: More Than Just 4K**
The new 4K smart set-top box isn't just about resolution. It supports 4K live broadcasts, on-demand content, time-shifted viewing, and more. It also integrates with China Telecom’s open platform, allowing users to connect external devices like voice remotes, cameras, and game controllers. This opens the door to voice control, video calls, and motion-controlled games.
**4. Voice Control with Zero Delay**
With the 4K upgrade, users can enjoy smarter voice control features. The new system uses XFX 5.0 AI technology, reducing voice input time by 95%. This means faster channel switching, quicker video loading, and precise voice commands that let you find what you want instantly.
In addition to hardware improvements, the software upgrade brings enhanced AI capabilities, making the whole experience more intuitive and user-friendly.
**Special 4K Experience Events**
To help users fully embrace the 4K revolution, Guangdong Tianyi HD has introduced free 4K experience events. They offer a wealth of high-quality 4K content, including monthly 4K concerts streamed live. You don’t need to buy concert tickets anymore—just sit back and enjoy the live performance from your living room.
As internet technology continues to evolve, 4K is becoming more mainstream, and user expectations are rising. Upgrading your set-top box is no longer a luxury—it's a necessity.
